Every research query you send to a cloud service leaves your office.
When you type a research question into Westlaw, Lexis, or any cloud based AI research tool, that query, along with enough context for the service to answer it, travels to a third party server. For most work that is an acceptable trade. For a firm handling sensitive matters, a client who has asked that nothing leave the office, or a practice that simply prefers not to send research strategy to a vendor, there is a different option: a Nevada legal corpus that searches on hardware your firm owns, returns the supporting passage for every answer, and tells you when the supporting passage cannot be found. This page explains what that covers, how it works, and where its limits are.
What the corpus covers
DilloLex ships its own Nevada corpus. The appliance searches:
- Nevada Supreme Court and Court of Appeals opinions. Published and unpublished Nevada appellate opinions. Coverage extends across the full historical run of digitized decisions, with ongoing additions as new opinions are released. The corpus uses the same text as publicly available sources; it is not a substitute for official reporters or a certified copy.
- Nevada Revised Statutes and Nevada Administrative Code. The full NRS and NAC text, indexed by chapter and section, searchable by natural language or by citation. The corpus reflects a dated snapshot; confirm the current enrolled text before relying on any specific provision.
- Nevada court rules. NRCP, NRAP, EDCR, NEFCR, RPC, and related local rules, as published by the Nevada Supreme Court and the district courts. Court rules change; always verify the current version before citing.
- Jury instructions and secondary sources. Nevada jury instructions, plus licensed practice guides, form commentaries, and reference materials the firm has ingested into the system. Coverage depends on what the firm has loaded.
The corpus does not include federal authority beyond what appears in Nevada appellate opinions. It does not include legislative history, administrative regulations outside the court rules, or the official NRS supplements between published editions. DilloLex covers Nevada law; firms that need broader coverage keep a service for it.
How a search works
You ask a question in plain language. The appliance searches the corpus using a combination of keyword and semantic matching, ranks the results by relevance, and returns a list of passages drawn from the actual source text. Each passage is labeled with its source: the opinion name and citation, the NRS section, or the rule number and subdivision. If the question touches citation treatment, the system checks whether a later Nevada opinion has overruled, criticized, distinguished, or limited the earlier case, and surfaces that information alongside the passage.
Every answer shows its source passage. If the corpus does not contain material that answers the question, the system says so rather than generating an answer without support. An answer without a cited source passage is a finding that the corpus does not contain responsive material, not an invitation to keep reading as if the question were answered.
The attorney reads the returned passages, follows the citations, and applies legal judgment to the research. The tool surfaces and organizes what is in the corpus. The legal analysis is the attorney's work.
Citation treatment: checking current status before you rely on a case
Finding a case is step one. Knowing whether a later Nevada court has undermined it is step two, and it is the step that attorneys under deadline pressure sometimes skip.
DilloLex checks a citation's treatment against a graph of Nevada appellate decisions. When you look up a case, the system reports whether any subsequent Nevada opinion has overruled it, criticized it, distinguished it on facts, or set it aside in a specific context. The result is a flag, not a legal conclusion: a case flagged as "criticized" may still be good law for the proposition you need. The flag tells you to read the criticizing opinion before you rely on the one you found. That reading and that judgment belong to you.
This citator function covers Nevada appellate decisions. It does not cover federal treatment of Nevada cases, subsequent legislative overruling, or administrative developments. Before relying on any Nevada authority in a filed document, confirm its current status against an authoritative source and read the opinions the citator flags.
The boundaries
DilloLex ships a defined Nevada corpus and states its limits plainly. What the firm runs alongside it, including whether it keeps or cancels Westlaw or Lexis, is the firm's decision.
- The corpus is a dated snapshot. New opinions, new NRS text, and amended court rules are not instantaneous. There is a lag between publication and indexing. Verify currency before relying on any authority for a filing.
- The system does not make legal determinations. It returns passages from the corpus that are responsive to your query. Whether those passages support your argument is a legal question the attorney answers.
- The system can miss relevant authority. No keyword or semantic search retrieves everything. A passage that is relevant to your question may not rank highly enough to appear in the results. Run multiple queries on the same issue and follow the citations the results surface.
- The citator is not a complete treatment history. It works from the Nevada appellate corpus. It does not account for federal court treatment of Nevada law, legislative changes to a statutory basis for a case, or authority from other jurisdictions that Nevada courts have not yet addressed.
- Secondary sources depend on what the firm has ingested. If a practice guide is not in the system, the system cannot find it.
A lawyer using this tool still verifies good law status before relying on any case in a filed document. The tool supports that verification; the judgment stays with the attorney.
The confidentiality difference
When you run a research query on the DilloLex appliance, that query runs on hardware your firm owns and controls. No client content goes to an outside AI. The appliance still connects to your firm's own cloud storage and to any managed tools your firm has selected, but the research query and the corpus it searches stay on the machine in your office.
One boundary is worth stating plainly. You still pull the full opinion text to read and cite it, and you still verify NRS text against the official enrolled version before filing. Those checks reach public court and legislative sites. But the question you asked, and what you were researching, never leaves your office as a query to a third party server. That is the difference.
The security page covers the full architecture, including how the appliance connects to your existing cloud storage and what stays local.
How DilloLex helps
DilloLex is software that assists the firm's staff. It does not practice law, and no output is a substitute for the attorney's independent legal judgment. What it does, on hardware the firm owns:
- Searches Nevada opinions, NRS text, court rules, and the firm's secondary sources in a single query, returning the supporting passage for each result.
- Reports citation treatment, flagging cases that subsequent Nevada opinions have overruled, criticized, or distinguished, so the attorney knows to read those opinions before relying on the earlier one.
- Declines to generate answers it cannot support from the corpus, so a result with no cited passage is a clear signal to look elsewhere rather than a confident answer that may be wrong.
- Keeps every query on the firm's own appliance, with no research content sent to an outside AI service.
The supervising attorney reviews each result, follows the citations, verifies currency, and makes the legal judgments. The system organizes and surfaces; the attorney decides.
If you want to run a research question through the appliance and see how the results look, book a demo. You can also read about how the appliance fits into a Nevada practice, the firm's data handling posture, pricing, or the related guides on the prefiling citation check and Bates numbering and production.
Common questions
Does DilloLex replace Westlaw or Lexis for Nevada research?
That is the firm's call. DilloLex ships its own Nevada corpus: Nevada Supreme Court and Court of Appeals opinions, the NRS and NAC, court rules, and jury instructions, plus the secondary sources the firm loads, all searched on the appliance in your office. It does not cover federal authority or other states, and Westlaw and Lexis offer research tools DilloLex does not. Some firms keep an outside subscription for that work; others decide the Nevada corpus covers their docket. DilloLex works the same either way.
How current is the Nevada corpus?
The corpus reflects a dated snapshot with periodic updates. New Nevada Supreme Court and Court of Appeals opinions are added as they are processed, but there is a lag. New NRS text and amended court rules require an update cycle as well. For any authority you plan to cite in a filing, verify the current version against the official source before relying on the text you found in the appliance. The corpus is a working text, not an official source.
What does "no client content goes to an outside AI" mean exactly?
It means the research query you type and the corpus it searches run on the appliance in your office. That query is not transmitted to a third party AI service. The appliance does connect to the internet for other purposes: your firm's cloud storage, calendar integrations, and any third party tools you have chosen to enable. The confidentiality benefit is specifically that your research questions and your client matter documents do not travel to a vendor's AI inference servers. For the full architecture, see the security page.
Can I rely on the citator result as a final good law check?
No. The citator covers Nevada appellate treatment of Nevada cases within the corpus. It does not cover federal court treatment, legislative overruling, administrative developments, or authority the corpus does not yet contain. Before relying on any case in a filed document, read the opinions the citator flags and confirm through an authoritative source that the case still stands for the proposition you need. The flag is a prompt to investigate, not a final answer.
What court rules does the corpus include?
The corpus includes NRCP, NRAP, EDCR, NEFCR, Nevada RPC, and the local rules of the Nevada district courts as published and indexed. Court rules are amended frequently; always verify the current version on the Nevada Supreme Court website or through your court's local rules page before citing any rule in a filing. This guide states rule names as general reference and is not a substitute for the current text. Confirm current Nevada rules before relying on anything described here.
